The satellite can run on only one battery, but it runs best if more than one battery is used. The variance a2 of lifetimes of these batteries affects the usefullifetime of the satellite before it goes dead. If the variance is too small, all the batteries will tend to die at once. Why? If the variance is too large, the batteries are simply not dependable. Why? Engineers havedetermined that a variance of o? = 23 months (squared) is most desirable for these batter les.

19 of 30 Ne II I have a dataset that lists the level of two blood proteins for each individual in a group of 100 people. My hypothesis is that the level of the first of these proteins depends on the level of the second protein. Assuming the levels of both proteins are Normally distributed, which of the following tests should I use to assess my hypothesis? 1-way ANOVA Paired, 2-tailed t-test O Spearman correlation Pearson correlation Unpaired, 2-tailed t-test
A manufacturer must test that his bolts are 4.00 cm long when they come off the assembly line. He must recalibrate his machines if the bolts are too long or too short. After sampling 121 randomly selected bolts off the assembly line, he calculates the sample mean to be 4.21 cm. He knows that the population standard deviation is 0.83 cm. Assuming a level of significance of 0.02, is there sufficient evidence to show that the manufacturer needs to recalibrate the machines? Step 3 of 3: Draw a conclusion and interpret the decision.

I need to turn this into a hypothesis test using a Ti84 As a dog owner I became curious as to the reason, why people choose to own a dog. I claim that more women choose to own a dog mainly for companionship than women who choose to have a large dog mainly for companionship. Do the data provide sufficient evidence to conclude that the proportion of women who prefer small dogs for companionship greater than the proportion of women who prefer large dogs for companionship? On Sunday, I will stand outside of my local Petco and survey women who are entering the store. I will ask if they own a dog, the main reason that they acquired a dog whether it was for protection or companionship and the size of their dog. I will collect this data in my notebook. I will not collect data from people exiting the store to ensure that I do not survey the same person more than once. I will acquire 30 samples of women who own small dogs and 30 women who own large dogs. I will not include women under the…
If the variance in the weights of one sample of 12 oz. cookies is 3 oz. and the variance in a second sample, made in another factory, is only 1 oz. is there a real difference in variances between the two? (Estimate at 95% probability level, using 2-tail test). Use the appropriate test statistic to determine this, and assume there are 9 degrees of freedom for each sample. Yes no maybe none of the above.
